  • What makes ticks so good at transmitting pathogens? Tick saliva can diminish immune responses enhancing pathogen establishment.
  • Can pathogens manipulate the salivary secretions of their vector? By hijacking extracellular vesicles, they appear to do so.
  • Can we exploit tick biology to design better vaccines? Using extracellular vesicles, we are discovering novel vaccine antigens.
  • How do ticks adapt to new environments and increase their survival to cold? What is the role of epigenetics in all of this?
